Heat 3 tablespoons of olive oil in a large Dutch oven over medium-high heat for exactly 2 minutes until shimmering. Season chicken pieces with salt and pepper, then brown them in batches for 3-4 minutes per side—don't crowd the pan, as this prevents proper browning. Transfer browned chicken to a plate and set aside.

In the same pot, add diced onion and cook for 2 minutes until softened and fragrant. Stir in minced garlic and cook for just 30 seconds—this prevents bitterness. Add carrots and baby potatoes, stirring constantly for 1 minute to coat with oil and develop flavor.

Pour in the dry white wine and scrape the bottom of the pot with a wooden spoon to release all caramelized bits—this adds depth. Let it reduce by half, approximately 2-3 minutes, concentrating the wine's acidity and alcohol content.

Return the chicken pieces to the pot along with chicken broth, thyme, and bay leaves, stirring gently to combine. Bring to a full boil for 1 minute, then reduce heat to a gentle simmer and cover with the lid. The elegant summer chicken stew recipe requires 30 minutes of simmering to ensure chicken reaches perfect tenderness and flavors meld beautifully.

After 30 minutes, add zucchini, green beans, and cherry tomatoes—these cook quickly and should remain slightly firm. Simmer uncovered for 12-15 minutes until all vegetables are tender-crisp and the chicken reaches internal temperature of 165°F. Remove from heat, stir in fresh basil and adjust seasoning with additional salt and pepper as needed.
